Low Permeability is the measure of the ability of less material to pass through

Aquifer Conified Aquifer Unconified Aquifer
An Aquifer is a body of permeable rock which can contain or transmit groundwater.
A Confined Aquifer is an aquifer below the land surface that is saturated with water.
Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer.

Saturation Zone Unsaturation Zone
The Saturation Zone is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturated with water.
The Unsaturation Zone is the part of the subsurface between the land surface and the groundwater table.

Precipitation Evaporation Transpiration Infiltration
Precipitation is any product of the condensation of atmospheric water vapor that falls under gravity
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor
Infiltration is the process by which water on the ground surface enters the soil

Sinkholes Caves CODs
(Cones of Depression)
a Sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer.
a Cave is a cavern in the ground. These can hold water, minerals, animals, etc. But most importantly, these can hold water from rivers, & streams.
a Cone of Depression occurs in an aquifer while the groundwater gets pumped from a well to the surface.
